Daily Challenge Tracker not working

At first nothing was working then I got into mut  then it wouldn't track any stats then it wouldn't give me anything for completing things then half that started working then they dropped most feared and back to nothing working then after the new update everything started working except the daily challenges and still don't get why we don't receive rewards for each level of solo battles. Legend is pointless just do mvp till you complete those then go to rookie and Stat gain. No incentive to play harder than that.
